Bondi suits interminable cycling, even tipsy? (7)
I believe the answer is:
bikinis
'bondi suits' is the definition.
I can't judge whether this definition defines the answer.
'interminable cycling even tipsy?' is the wordplay.
'interminable' means to remove the last letter (without the letter which terminates the word).
'cycling' becomes 'biking' ('bike' can be a synonym of 'cycle').
'even' means one should take alternating letters (even-numbered letters are used).
The alternate letters of 'tipsy' are 'is'.
'biking' with its final letter taken off is 'bikin'.
'bikin'+'is'='BIKINIS'
Can you help me to learn more?
(Other definitions for bikinis that I've seen before include "gear in summer?" , "sportswear" , "ladieswear" .)
